The joker ideas just came to me. i then thought of mature-rated fatalities for the DC characters.

sorry if its in the wrong section

Joker
- squirts acid on the vics face. the guy then runs around in pain when suddenly Joker pulls out that boxing glove thing punching the head off
- joker dumps gas on the vic and lights him on fire. he starts chuckling when the vic runs around then laughs his familiar laugh

Superman
- grabs the guys arms and holds them sideways to the vic. he pulls slowly but with great force until... there are two pieces
- grabs the guys head with both hands and crushes

batman
- throws a batarang at the guys foot which explodes. trying to crawl away, bats fires a grappling hook through the non-blowned leg dragging him back. he pierces a batarang from the top of the skull to the ground

The Flash
- grabs the face then runs around the guy. the vics body then falls with the flash still holding his head
- quick punches to the gut making the vic bend over. flash uppercuts the guy to his back then pummels the head to a mushy pulp. litterally

Green Lantern
- sends a sword vertically to stab the vic. the sword then starts pushing sideways
- shackles the vic's wrists and ankles and they start pulling off one by one. then sends energy into the wounds to the head exploding it
- the rack from saw 3

Catwoman
- does what B.Orchid does in Killer instinct. im sure this is mature-rated

Deathstroke
- shoots the vic's foot. yelping in pain, he stabs the vic in his open mouth exiting the back of the brain

Luthor
- punches the guy on his back then fires a laser slicing the enemy like in James Bond

Captain Marvel
- punches his hand through the chest while grabbing the heart
